Introduction

How Changing the Temperature of Acid Effects the Rate of Gas Produced Introduction I am going to investigate that if altering the temperature of Hydrochloric acid in the company of magnesium has an effect of how much hydrogen is produced. My Prediction I predict that as the temperature of the hydrochloric acid increasers the rate of reaction will rise and when the acid is at an average temperature the reaction will be decreased. This might happen because when the temperature increases the fraction of molecules that can provide the commencement energy needed for reaction becomes larger as the temperate increases. So if the atom of the acid has more energy that means that they will vibrate faster than normal and if they vibrate quicker they will hit or will collide. As the molecules will be colliding with each other, some atoms will escape because as the temperature increases, the atoms will be more violent and move rapidly. The atoms will escape into the air, from the reaction. This happens because the substances transfer energy from places where the temperature is higher to places where the temperature is lower. In this experiment, the two elements are magnesium and hydrochloric acid. ...read more.

* After that I will see how far the gas moves in the measuring cylinder every minute up to five minutes. * I will do the same investigation again but this time the temperatures of the acid will be different.

Conclusion

I think the way I worked was good and very fast but I don't think I did it accurately because I had to rush it through to get time and do each experiment 2 times to get a more reliable results. So, I managed to get a more reliable result but not very accurate. I got some anomalous results for the acid being at 80�C because it should react faster than the acid at 30�C because it's hotter and it will have more energy, but it didn't. It was completely the opposite. This might happen because I rushed it through and didn't heat to the exact temperature or it cooled down faster than the acid at 70�C maybe because the air conditioner was put back on again. To improve my investigation I should have extended it and did more experiments to get a good set of results and to be more accurate while doing them. Also, I can improve it by getting all the amount of magnesium ribbon needed and all the hydraulic acid needed, and to use up the time I should put some test tubes in the water bath or in ice to get to the temperature needed while doing another experiment because then I wouldn't have to wait and waste time for the acid to get to the temperature needed.

    Controlled Amount of HCl This must be kept constant as different amounts of the acid would make the test unfair and the results therefore unreliable. If there is too much, the speed of the reaction will increase because there is more acid to react with the marble chips.

    Analyzing the relationship between concentration and heat evolved During a neutralization reaction, heat is given out. Because neutralization reaction is basically the bond formation between the H+ and OH- ions, bond formation always gives out energy, so neutralization reaction gives out energy.

    Another reason for a stronger acid producing a higher value for the heat of neutralisation is because it has more free H+ ions. I have deduced this because it is known that in a strong acid, all of the molecules are dissociated into their component ions.
